Lymphomas are cancers of a specific type of white blood cells known as lymphocytes. These cells help fight infections. Lymphomas can develop from either B or T lymphocytes. T lymphocytes are important in regulating the immune system and in fighting viral infections. B lymphocytes produce antibodies, which are essential in fighting off some infections.
Lymphocytes move about to all parts of the body through the bloodstream and through a network of tubular channels called lymphatic vessels. Scattered throughout the network of lymphatic vessels are lymph nodes, which house collections of lymphocytes. Lymphocytes that become cancerous (lymphoma cells) may remain confined to a single lymph node or may spread to the bone marrow, blood, the spleen, or virtually any other organ.
The two major types of lymphoma are
Non-Hodgkin lymphomas are more common than Hodgkin lymphoma. There are many subtypes of non-Hodgkin lymphoma.
